These valves give control over flow, pressure and load holding in a high-pressure hydraulic system. The range includes needle valves, load-lowering check valves with manual bypass, a pilot-operated check valve, an adjustable relief valve and a stainless ball valve.
The VCB-2 counterbalance valve gives smooth lifting and lowering of heavy loads with double-acting cylinders. The VCB-3 is a manifold version for Durapac power units.
For running several cylinders from one pump, VMN needle-valve manifolds come with 2 or 4 outlets in aluminum or steel. RM-7 return manifolds are also available.
